Not quite sure what that means Tulsa. The Nikon D90 will autofocus with any AF-Nikkor, with any AF-D Nikkor, with any AF-i Nikkor, and with any AF-S Nikkor, of either the D-type with aperture rings, or the newer G-style lenses with no aperture ring on the lens barrel. In other words, every single Nikon autofocus lens made for "regular" Nikon cameras since the mid-1980s (that excludes the Nikon F3AF which had its very-own,body-specific lenses) will focus on a Nikon D90. Same goes for the D50,D70,D80,D100,D200,D300,The D1 series, the D2 series, the D3 series, and the D700.

All of the cameras I listed have an in-body autofocusing motor. Those cameras will focus screw-drive focusing lenses, and in-body AF motor models. From Nikon, Tamron,Sigma,Tokina,Quantaray,etc. Of course, the D90 will not autofocus manual focusing lenses.

Just as an aside, Nikon made a TC16 that converted MANUAL focusing lenses to autofocusing lenses on some of the earlier cameras. I have one somewhere around here...
